As a hobbyist (and an electronic noob) I'm wondering if having a logic analyzer would help me to better understand digital/analog signals and identify problems

I don't want to spend too much money as I'm not a pro, and found these analyzers from a French company (could be better for customer service, as this is the country I live in)

The SQ50 is around 100$ (89), what do you think about this model ?

And another question : are the standard probes provided with any logic analyzer "compatible" with breadboards hole format ?
